ASH-SIFTER.

SPECIFICATION forming part of Letters Patent No. 545,094, dated August27, 1895.

Application tiled March ZO, 1895.

To ctZZ whom, t may concern:

Be it known that I, JOHN G. P. PUTNAM, a citizen of the United States,residing at Claremont, in the countyof Sullivan and State of NewHampshire, have invented a new and useful Ash-Sifter, of which thefollowing is a specification. v

The invention relatesto improvements in ash-sitters.

The object of the present invention is to improve the construction ofsitters, and to provide a simple and inexpensive one adapted for rapidlyand conveniently sifting ashes and other material, and capable ofenabling the sifted material to be readily discharged from the rotarycylindrical sieve.

The invention consists in the construction and novel combination andarrangement of parts hereinafter fully described, illustrated in theaccompanying drawings, and pointed out in the claim hereto appended.

In the drawings, Figure l is an elevation ot' an ash-sifter constructedin accordance with this invention.- Fig. 2 is a vertical sectional viewtaken longitudinally of the cylindrical sieve. Fig. 3 is a similar viewtaken transversely of the cylindrical sieve. Fig. 4 is a detailperspective view of aportion of the cylindrical sieve, showing one ofthe catches. Fig. 5 is an enlarged detail sectional View of one of thecatches.

Like numerals of reference indicate eorrespending parts in all thetigures of the drawings.

l designates a sitter, comprising a casing 2 and a rotary cylindricalsieve 3, removably journaled in the casing. The casing is composed of alower body portion and a semicylindrical cover 4, removably mounted onthe body portion. The body portion is rectangular, and is provided atthe base with a cylindrical cap 5, adapted to t over the open end of abarrel, whereby the sitter is mounted thereon. The rotary cylindricalsieve has a periphery of wire-netting, or the like, and comprises a bodyportion 6 and a segmental section or lid 7, which is hinged at one sideat S to the body portion 6. The body portion is provided at its endswith catches for holding the lid or hinged section 7 closed, and eachcatch comprises a slotted Serial No. 542,529. (No model.)

resilient plate 9 for engaging a lug l0 of the hinged section or lid,and a projecting supporting-plate 11, arranged adjacent to the resilientplate 9. exterior or outer face of the end of the lid or hinged section,and the resilient plate 9 is also located on the outer face of the endof the body portion of the sieve, and the free end of the plate 9 iscurved or bent outward. The plate 11 is located on the inner face of theend of the body portion of the sieve and has its upper or outer end bentin- Ward, and the oppositely-bent upper ends of the plates 9 and l1 forma tlaring mouth or entrance to the space between the plates. The end ofthe hinged .section or lid is re ceived between the plates 9 and 11, thebent ends of the latter forming a flaring mouth to receive the lid orhinged section, and the plate l1 prevents any accidental disengagementof the lug. The slot l2 of the plate 9 extends longitudinally of thesame, and the lug l0 is beveled to enable it to force the spring-plateoutward in order to engage the slot thereof. The lid or hinged sectionmay be readily swung open by forcing the springplate outward suiiicientto release the lugs 10. The journals of the cylindrical sieve arepreterably formed by a shaft 14, fixed to the body portion of the sieveand having one of its ends extended and formed into a crank-han dielocated on the exterior ofl the casing.

The lug is arranged on thev It will be `seen that the sitter is simpleand i comparatively inexpensive in construction, that it is adapted foroperating on all kinds of'rnaterial, and that the catches for holdingthe sections of the cylindrical sieve closed are strong and durable andare readily manipulated. y

Changes in the form, proportion, and the minor details of constructionmay be resorted to without departing from the principle .or sacrificingany of the advantages ot this .in-

vention.

In a sitter, the combination of a casing, a cylindrical sieve journaledtherein and provided with a hinged section or lid, and catches locatedat each end of the cylindrical sieve and each comprising a resilientplate mounted on the exterior of the body portion of the IGO sieve andprovided with a slot and having its upper free end curved outward, asupporting plate mounted on the interior of the body portion andarranged adjacent to the resilient plate, and having its upper endcurved inward, and co-operating with the outwardly curved end of theresilient plate to form a iiaring mouth or entrance to the space betweenthe plates and a lug mounted on the ro exterior of the lid or hingedsection 'and having a beveled portion and engaging the slot of theplate, substantially as described.

In testimony that I claim the foregoing as my own I have hereto axed mysignature in the presence of two witnesses.
